A self sustaining prison to lock up sims here is how it works you need a #warden and a officer move them in to the lot, next choose a #convict from a family in the game and split them from the #household and move them in to the #prison, transfer $10000(Fine) from their household while doing this. Lock door(For convict) to the outside,warden office bookshelf door,cafeteria door. Lastly make them paint,wood shop and sell the profits to pay the bills.
